Being a beta version, the OxygenOS Open Beta 1 for the OnePlus 6 has some known issues. OnePlus says that some applications may not function as expected when running on this beta version. Similarly, Google Pay service won't work after installing the latest beta version, and you may see a "Device is not Certified by Google" message when accessing Google Play.
